okay so as a global i elcare

code:

struct catstats
{

      int c;   // count of items
      float t; // total of items

};


and then in main

void main()
{

      catstats n, p; //positive and negative                     catstat structures



    cin >> num;

    x_positive( num, structure& p? );
    x_negative( num, structure& n?
}

Okay so I think n and p makes it that there's 2 separate structures declared for 'positive' and negative numbers, but I'm trying to figure out how do I pass the structures by reference.

Like in x_positive I want to calc the 'counter' and the 'total' of the pos/neg #'s I passed.

example:

code:

void x_positive( anum, structure& p? )
{


      c++;
      t = t + anum;

      PrintCat();

}

Like if the variables are already declared in the struct catstates, how do I get it so that they're passed right? I thought func( num, catstats& p )

did it but apparently not.

okay I think I figured it out I can do catstats p.c

:edit:

blah full or errors.

:double edit: okay now I think I gots it wokring

I'm not sure if you still need the help, but here's two things that are coming to mind in your code.
In your function I don't think you are actually changing any members of p. I'm not totally sure why this would compile in the first place, but you should be doing p.c++ and p.t+= anum or some such thing.

Also, what is x_negative going that requires a separate function?

oops, double post, sorry

Posted by Blayne Bradley (Member # 8565) on :

negative deals with negative numbers entered, positiv vice versa.

Not according to the code you posted. There's no check anywhere to ensure that only positive numbers get passed to x_positive. What's this code supposed to do, anyway?

i passed psuodo code, I only wanted help with passing structures, and it works fine now, im onto version 5ish now out of 6.
